2-(N-Morpholino) ethanesulfonic acid,monohydrate (MES) CAS 4432-31-9

Introduction

MES, also known as 2-morpholineethanesulfonic acid, has a CAS of 4432-31-9. It is a binary buffer with good buffering capacity and chemical stability. It is widely used in biochemistry and molecular biology experiments, such as cell culture, enzyme activity determination, electrophoresis and protein research.

MES can maintain the stability of the solution within a certain pH range and prevent the influence of pH fluctuations on the experimental results. Its pKa value is about 6.1, which is suitable for experiments in the acidic pH range (pH 5.5-6.7). At the same time, it has good stability to metal ions, which can reduce their interference with experimental results.
